Abstract

PROBLEM TO BE SOLVED: To provide a footstep which enables to rise and fall with safety by forming a tread at the tip on both sides and in the intermediate part and further extending the tread at the tip on both ends and then bending inwardly the tread and connecting that to the intermediate part on the side. SOLUTION: Except for a leg 3, an iron-made core bar 2 is covered with a synthetic resin 4, thereby forming a footstep 1. Treads 5 and 6 are formed at the tip of both sides 7 of the footstep 1 and the intermediate part. Non-slip patterns 8 and 9 are formed on the top of the treads 5 and 6 while a grip 10 is formed on the tread 5. After the tread 5 at the tip is further extended on both ends, it is inwardly bent in the rear so that it may be connected to the intermediate part of the sides 7. A large number of footsteps are set up in the vertical direction on a manhole or a bulkhead or the like. Therefore, this construction makes it possible for any one who rises and falls, to climb up and down with his or her feet with safety extendingly in contact with the tread.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot-holding tool for use in manholes, seawalls, etc. having a foot portion and side portions and legs located on both sides thereof.

[0002]

2. Description of the Related Art As shown in, for example, Japanese Utility Model Publication No. 4-4040, a conventional footrest of this type is formed in a substantially U-shape in plan view with a foot portion and side portions located on both sides thereof. Things are commonly known.

[0003]

By the way, in the above-mentioned publicly known device, a large number of these footrests are arranged vertically in a manhole, a seawall, etc., and the manholes, seawalls, etc. are utilized by utilizing the footrests. When moving up and down, it is unstable because one foot is placed on the foot, and the range of foot on the foot is narrow. There is a risk of slipping your feet out of the area.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is to extend the length of the foot portion and to use two foot portions. An object of the present invention is to provide a footrest that can be lifted and lowered in a stable state without the foot of an elevating person stepping off from the foot when the foot is lifted and lowered.

[0005]

In order to achieve the above-mentioned object, a footrest according to the present invention has footsteps formed at the tip and the middle of both sides, and the tipsteps on the tip side are further provided at both ends. After being stretched, it is bent backward inward and connected to the intermediate portion of the side portion.

Further, the present invention is characterized in that a reflector element is formed by attaching and coupling the reflector element to the bent portion from above and below.

[0007]

1 to 3 relate to an embodiment of the present invention, FIG. 1 is a plan view of a footrest, FIG. 2 is a front view thereof, and FIG. 3 is A--A of FIG. It is a sectional view.

In the figure, reference numeral 1 denotes the entire footrest, and the footrest 1 is made of polypropylene, except for its legs 3, with respect to an iron cored bar 2 which is substantially U-shaped in plan view. It is basically based on a synthetic resin 4 such as rustproof coating. The footrest 1 is fixed to the manhole or seawall with the portion of the leg portion 3 not covered with the synthetic resin 4 embedded in, for example, a concrete of the seawall or seawall. Is what is done.

Numerals 5 and 6 are foot portions formed on the footrest 1, reference numeral 7 is a side portion, the foot portions 5 are at the tips of both side portions 7, 7, and the foot portions 6 are on both sides. It is connected to the middle part of the parts 7, 7. A large number of anti-slip patterns 8 and 9 are formed on the upper surfaces of the footsteps 5 and 6 in the axial direction so that the foot of the lifter does not slip. A corrugated grip portion 10 is formed on one side surface of the foot portion 5 in the axial direction so that the foot portion 5 can be gripped by a hand.

The foot portion 5 is further extended from the position where it is connected to the tips of the side portions 7 and 7, and the extended portions 11 and 1 are extended.
1, the end portion of the extension portion 11 is bent to the rear inside 12 and is connected to the middle portion of the side portion.

Since the footrest having the above-described structure is used, a large number of the footrests 1 are vertically installed on a manhole, a seawall, etc., and when the footrests 1 are used to move up and down. In addition, the elevating person sequentially puts his / her feet on the footsteps 5 and 6 of the footrest 1 and ascends / descends, and at that time, the foot moves up and down while contacting both footsteps 5 and 6. As a result, stable lifting and lowering is possible. Further, since the foot step portion 5 is provided so as to extend further outward than between the both side portions 7, 7, it is longer than that of the conventional foot step portion, and even when it is quickly moved up and down, Less likely to miss your foot.

Then, the reflector 13 is replaced by the two reflector elements 1
4 and 15, the reflector elements 14 and 15 are attached to and coupled to the bend 12 from above and below, and a reflector 13 is formed.
In such a case, the position and arrangement of the footrests 1 provided on the revetment in a dark manhole or at night can be confirmed from any direction, and the reflector 13 can be easily replaced, resulting in a safer footrest.

[0013]

According to the first aspect of the present invention, when ascending and descending using a footrest, it is possible for the person of the elevating person to ascend and descend while straddling both foot portions. It becomes a footrest that can be moved up and down stably. Also, since the foot portion is provided to extend further outward than between the two side portions,
The footrest is longer than the conventional footrest and is less likely to step off the foot from the foot even when moving up and down quickly.

Further, according to the present invention described in claim 2,
While expecting the above effects, the presence of the reflector makes the replacement of the reflector easier and a safer footrest.
